Portrait of the Marquis Paul Galuccio de L’Hôpital Louis Jean François Lagrenée (1725-1805)

The picture has something of this: portrait, people, man, wear, elderly, jacket, coat, lid, leader, outerwear, scientist, woman, facial expression, writer, mustache, scarf.
Perhaps it’s a painting of a man in a green coat with a fur stole around his neck and a fur collar.
